Abstract

본 발명은 투사형 액정 표시장치에 열전도막을 형성시키고 열전도막에 의해 다수의 펠티어 소자가 전기적으로 제어되게 하여 펠티어소자 자체에 의한 냉각방식을 이용한 투사형 액정 표시장치이며, 열전도막은 액정 패널 표면의 화상제공 부분을 제외한 표면의 테두리 부분이나, 액정 패널 내부의 화소 부위에 설치 가능하고, 열전도막에 펠티어 소자를 연결시켜 냉각시키므로 기존의 공냉팬 방식에 비하여 소음이 없어 노이즈가 제거되고 경량화가 가능하며 소모전력등도 해결할 수 있다.The present invention is a projection type liquid crystal display device using a cooling method by the Peltier element itself by forming a thermal conductive film on the projection type liquid crystal display device and allowing a plurality of Peltier elements to be electrically controlled by the thermal conductive film. It can be installed on the edge of the surface except the inside of the liquid crystal panel or the pixel area inside the liquid crystal panel, and the Peltier element is connected to the heat conduction film to cool it. Can also be solved.
